Moonchild — Kate L. Mary

In a world fueled by greed and corruption, where airships rule the skies and coalmines have been turned into prisons, Scarlett Moon has one goal: Survive. Being tough and looking out for herself is the only way to stay alive, but when her best friend, Rory, is arrested and returned to the mines, all of Scarlett's carefully built walls threaten to crumble. After being rescued by an airship full of pirates, led by the sexy and irresistible Asher Kimura, Scarlett finds herself surrounded by cons and fugitives, and thrust into the middle of a coal-smuggling business. When they take her to Columbus, the one place she never wanted to set foot in again, she wants nothing more than to get away. And her discomfort only grows as she becomes increasingly drawn to Asher. But everything changes when she discovers there may be a way to rescue Rory. Enlisting the pirates' help, Scarlett sets out on a mission to save her friend, praying that her overwhelming attraction to Asher doesn't mean the end to her freedom -- in more ways than one.
